Abstract
The effects of combined shear and torsion on reinforced concrete beams have been of much interest among civil engineers and researchers. To study the reinforced concrete beams, a suitable set up system is needed. In present investigation, a set up system has been built and evaluated based on structure analysis aspects. Evaluation is done by testing 5 beams which had actual sizes and an area of weaker section in their span. The samples were tested under different eccentricities, varied from zero (pure shear) to infinity (pure torsion). Among the advantages of this test set up, the possibility of testing the samples under pure shear, pure torsion and combined shear and torsion can be mentioned. Results showed that the set up worked properly and the shear-torsion interaction curve was linear.
